Another object of the invent-ion is to provide an article of this kind so constructed that the lower open e'nd'thereof will be properly maintained in position for trapping fish as the net is being lowered in the water.

Another object of the invention is'to vpro- Vide a trap of this nature having novel means for closing the same after it has reached 'a predetermined depth in order that when the trap is elevated the fish will'be prevented from escaping from the trap." g V With these and other ob ects in view, th1s invention resides in the novel features of construction, formation, combination and ar rangement of parts 'tobe hereinafter more 'fully described, claimed and illustrated in the accompanying'drawings, in which:

the same in its trapping position. Figure 2 is a'vertical sectional view showing the condition of the trap'when beingelevated. r g V Figure 3 is adetail sectional View of the sto.f F igure 4 is a perspective view ofone ofthe V spreading plates.

Referring to the drawings, designates the net which is of bag-like form,said netbeing;

formed of suitable cord and restricted at its 4o upperend. Secured in the restricted upper end is a metallic guide ring 2, the purpose of which will appearlater.} The lower end ,of thenet is bound with a'cord 3 which issecured I Also secured to the secured to their under surfaces. These plates so may be secured to the cord 3 inianyapprroved the water the above mentioned guide ring 2 V cord '3 of netare. metallic plates?) having weights '6 suitably i929. Serial no. 363,196,

TO AN! manner and serve to spread the cord so that 7 said cord will assume asubstantially circular condition as the a trap is loweredint'othe water. j l g Amain cord 7 is provided and has its'lower endfix'ed'in the stop'9, said stop being formed :fro'mwood or any other suitable ma 'terial,-'and connected with this stop is aplu= Y:

rality of drawcords 10 which have their lowfreely slidable in the ring 2 and whenthe cord is pulled upwardly to lift the net the stop 9 I engages the ring 2 and causes the draw cords 10 to contract the COId3j-Hl1dQlOS8 the net as r .65 Y In Figur '1io'flthe'drawings, the .net is shown in'Figure 2; I

shown in a position after the same has-been that the weights Gare secured to the under lowered in the. water; It will be obvious'that 1 V as the net inka the plates 5," due to the fact surfaces thereof, will tend to hold the cord 3 in circular formation so that when the net is being lowered, fish will be trapped after Passingthroughthe lower open end of the net; l g

Sincethe cord 3 assumes a circular "formation as the net is belnglowered, fish encountered during-the downward movement ofthe net V will enter thereinto. 5

' When the net is about to be 3 will becontracted and the plates 5 andsink- Howevenias the net is lowered in thewater well as'those nearthe river bed.

Itwill thus bejseen that a trap vided wherein hooks are eliminated so that the fish trapped will be in'no way inutilated..;

From the foregoingitisthought that the operation and many-advantages ofthe hereini I i a described'inventionjwillbeapparentto those I skilled intheartwithout further description and it will be understood that various changes lowered into carried by the restricted endis pulled up wardlyon the cord 7, at which time thecord ha'slbeen prof in size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What is claimed is:

l. A fish trap comprising a net of bag-like formation, said net having a ring in its upper end, a cord binding the lower end of the net to provide an entrance opening, weighted 3 plates secured to the; cord, a main cord slidabie in the ring and having a stop carried by its lower end, draw-strings connecting the plates and stop, said stop being adapted to engage the ring to lift the net and simulta- 15 :ieously contract the cord forming the entrance opening, as and for the purpose set forth. 7

2. A fish trap comprising a net of bag-like formation having a restricted upper end pro- 539 Vvided with a ring and having a lower open 7 end bound by a cord providing an entrance opening, a main cord slidable in the ring and having a stop connected to its lower end, draw cords connecting the first named cord and i, 3 said stop, sinkers carried by thefirst named cord, said main cord being operable during upward movement of the net to close the open end thereof. 7

" 3. A fish trap comprising a net of bag-like formation having a restricted upper end, a

ringsecured in saidend, said net having an o'p-en lower end bound by a cord, Weighted plates secured to the cord, a main cord slidable in'the ring and having a stop upon its Eower'end, draw cords connecting the stop and first named cord, said stop being adapted to engage the ring when the main cord is pulled upwardly, said step, when moved upwardly, serving to cause the draw cords to n, contract said cord and told a portion of the net.

"In testimony whereof I aiiix signature.
